I dont think OAI has any bad intentions with removing 5.3. And I dont think its fair to be calling out @vb as if they are responsible for this either. they have only been trying to help and be part of this community. I can understand frustration about the model being gone, but I think its also ok to trust the process. I have not had any bad experiences since 5.3 went away, but I respect that this is a major issue for others. I am sure the team is well aware of these frustrations and again i think we should just trust the process and see what they bring next. With the advancements they have been making so quickly already, i dont doubt what the bring next will make users forget about 5.3 not long after.
